Things would start to break.  Incorrect files or revisions might be 
checked out, files or revisions might not be checked in or synchronised. 
  Depends where the collision is.

You could consider extending the hash length.

If you do, then you hopefully also realise that there's not very much 
point in considering the answers to these questions...
